SECTIONAL WATER-HEATER AND BOILER.

SPECIFICATION forming part of Letters Patent No. 676,340, dated June 11,1901.

Application filed March 19, 1900. Serial No. 9,302. (No model.)

To all whom it may concern:

Be it known that VI, SAMUEL E. PORTER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin,have invented certain'new and useful Improvements in SectionalWater- Heaters and Boilers, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof.

My invention relates to sectional boilers and Water-heaters of the kindshown in United States Letters Patent No. 638,202, dated November 28,1899.

The object of the present invention is to afford easy access between thecross-tubes in such a heater for the purpose of cleaning out the sideflues and removing the dust and soot which has been found to lodge andcollect more or less upon said tubes.

It consists in a certain novel construction and arrangement of partshereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts inboth figures.

Figure 1 is a vertical longitudinal section of the heater, taken vin abroken plane indicated by the line 1 1 on Fig. 2, cutting the threemiddle sections through the cross-tubes at one side of the center andthe remaining sections centrally through the main fiues; and Fig. 2 is avertical cross-section of the heater, taken in a broken plane indicatedby the line 2 2, Fig. 1, passing between two adjoining sections to theleft of the line 1 1 and cutting one of the sections centrally'to theright of the line 1 1.

My improved boiler or heater is composed of a number of hollow cast ironsections joined together face to face. Each of the intermediate sectionsconsists of two upright side columns or water-legs A A, which areconnected at their upper ends by a hollow arch B, two intermediateupright hollow'columns O O, connected at their upper ends by a hollowweb h with the arch B, and crosstubes D D, connecting the columns A andO on each side of the heater. The outer columns A are extended at theirlower ends below the intermediate columns O and the lower bottoms andalternate with the tubes D.

tubes D D and form the sides of the fire-box E. The space between thecolumns C O, opening through the several intermediate sections, isseparated from the fire-box E and divided into two flues F and G, whichrun lengthwise through the upper part of the heater, by hollow crossconnections c c. The columnsA and O and the arch B of each section areof the same dimension lengthwise of the heater, so that when the severalsections are assembled, as shown in Fig. 1, their faces will form closedjoints. The cross-tubes D of each section are preferably made prismaticor diamond shape or with sides projecting beyond their tops and whichhave longitudinally concaved or recessed sides. The tubes D on one sideof each section preferably alternate with tubes D on the other side ofthe same section, so that a single pattern may be used for all of theintermediate sections, and by reversing every other one in assemblingthem thetubes D of each section will be directly opposite the tubes D'of the adjoining sections, the lateral angles or projecting sides oftheone being presented toward the recessed sides of the other, so as toform zigzag passages d d, leading upwardly from the fire-.box E throughthe spaces between the webs b into the upper fiue E. The

`openings between the tubes D D in the several sections are arrangedopposite or horizontally in `line with each other, as shown in Fig. 1,so that a brush may be passed through them from one end of the heater tothe other and dust and soot lodging and collecting upon said tubes maybe readily removed therefrom.

The tubes D D are preferably inclined downwardly toward. their outerends, so as to accelerate the circulation of the water from the outercolumns A to the inner columns C and to prevent the deposit of sedimentand the formation of scale upon the heat-absorbing walls of said tubes.

The `front and back sections have hollow webs b b', extending from topto bottom, with plain outer walls and inner walls having crossprojections on each side corresponding with the adjacent halves ofalternate crosstubes D and D' of the adjoining sections.

1 The heater may be made with a single'main flue extending lengthwisethrough it by omitting the upper cross connect-ions c between theintermediate columns C C when an indirect draft is not desired; but whenit is made with two ues, as shown in the draw-v ings, the upper crossconnection cis omitted from the front section and one or more of theintermediate sections next to it to afford free communication betweenthe ilues F and G at the front of the heater. At their rear ends theiiues F and G open into a smoke-box H, attached to the back section andprovided at or near its upper end with a flanged opening h for theattachment of the smoke-pipe. The upper iiue opening into said smoke-boxis provided with a damper L, by means of which direct communication maybe established between the upper flue F and the smoke-pipe or indirectcommunication by way of the lower flue G. The smoke-box H is alsoprovided with a check-damper M.

I is a door plate or frame attached to the front section and providedwith doors J and K, opening, respectively, into the front ends of thefines F and G, the spaces between the cross-tubes D and D', and there-box E. Preferably separate clean-out door-openings and doors J areprovided for the lues F and4 G and for the flue openings betweenthetubes D and D on each side of the heater.

N is a rectangular cast-iron base upon which the sections of the heaterare mounted. It forms the ash-pit and is provided at the top with agrate O of the usual or any suitable construction for heaters of thisclass. The door-plate I may be extended at the bottom over the base andprovided with an ashpit door P.

The water-spaces, in the several sections of which the heater iscomposed, communicate with each other through openings a a in theadjoining faces of said sections at or near the lower ends of thecolumns A and at or near the middle of the arches B B, and the sectionsare preferably secured to each other by means Vot' short bolts passingthrough ears a', cast on the sections, as shown in Fig. 2. To allow forunequal expansion and contraction, to maintain tight joints, and preventleakage, the openings a a may be provided with plain slipnipples a2,tted in said openings.

Q designates the return or water inlet or supply pipe, 'which may beconnected with the opening a in the lower end of the water leg orcolumn'A at either end and on either side of the heater. If desired, anumber of return or supply pipes may be used. o

R designates an outlet or service pipe, which may be connected, asshown, with the opening a in the arch B at either end of the heater,

or one or more such pipes may be connected i with any of the sectionsthrough the tops of the arches of intermediate sections or the outersides of the arches of the front and back sections.

By the construction and arrangement of the Hue-spaces and water-passagesof the sections, as hereinbefore described, extended heat-absorbingsurfaces are exposed directly to the action of the fire, which is drawnupwardly from the iire-box through the sinuous passages cZ between thecolumns A and O and the cross-tubes D D on each side ofthe heater intothe iiue F.

It will be obvious that heaters of different sizes and capacities may bebuilt up of like vsections on the plan herein described by assemblingmore or less sections, as required, and providing bases-of differentlengths.

The draft lor course of the products of combustion from the fire-box Eto the smoke-pipe is indicated by arrows on the drawings'.

AVarious changes in minor details of construction may be made withoutmaterially affecting the principle and mode ot' operation of the heaterand without departing from the spirit and' intended scope of myinvention.
